1st person to answer gets which expression represents 25x^2-81in factored form, and how? a.(5x+3)(5x-3)b.(5x-9)(5x-9)c.(5x+9 )(5x-9)
Answers: 2
is the difference of two squares, 
and 81. This means that we can use the formula for the difference of two squares, which is:
and 
. Taking the square root of both sides of the equations means that we will get the following:
